Tired of JSON viewers that turn multi-line strings into unreadable messes? I built JSON Light to solve exactly this problem.

The Problem

Most JSON viewers display multi-line strings as one long line with literal \n characters instead of actual line breaks. This makes reading descriptions, error messages, or any formatted text incredibly frustrating.

The Solution

JSON Light features a simple “View Raw” button (R) next to string values. Click it, and your multi-line strings display with proper formatting – line breaks, indentation, and all.

Key Features

• Raw String Display: Toggle between escaped and formatted text
• JSONL Support: Navigate JSON Lines files line by line
• File Format Support: Support for JSON, JSONL, and GeoJSON files
• Browser-Based: No installation needed, data stays local

Perfect for API documentation, log analysis, LLM prompt engineering, and debugging where you need to actually read the content in your JSON.
